We all expect to buy tiers as they wear thin and age. What if, however, we never had to do that? Also, what if there were no holes to repair from nails or other road debris?
When I started reading that, I thought: Hey, they'll have nanobots working around the clock making sure each tire is in perfect condition. But I guess this is still sci-fi. :) We'll settle with Michelin's new super-tires then.
